Definitions
- Such operations of the video data input unit 13 and the timing control unit 14 are controlled and processed together with the operation of the other components constituting the operation position judgment unit 10 by using various registers provided within a work memory 38, as the operator designates a program in a program memory 37 stored by a central processing unit (CPU) 36 via the bus 35 using a key input board 39.
- CPU central processing unit
- the cursor position is retained at a cursor position register RG1 of the work memory 38.
- the CPU 36 compares the input operation pattern of the input operation pattern register RG5 with the reference input operation pattern of a reference input operation pattern register RG5.
- a response command signal INST2 is supplied to a control signal generation unit 40.
- a response operation demanded by the operator by means of input operation to the input unit 12 is executed by the response operation unit 41 which is provided as external control equipment to the operation input system 1.
- occurrence of no change means that the operator has not performed an input operation to the input operation unit 12.
- the CPU 36 repeats processing of the loop of steps SP4-SP5-SP3-SP4 with respect to the mark indication MKj for which the change has not occurred, and updates the judgment reference value of the judgment reference value data register RG3 at step SP5. Whereby, it retains such a reference value that the judgment reference value data of the judgment reference value data register RG3 is continually changed in accordance with drift of brightness of the input operation unit 12 at a plurality of monitor cycles.
- this fact means that an input operation has not been effected at the input operation unit 12.
- the CPU 36 proceeds to step SP10 where the judgment reference value data corresponding to the mark indication MKj is updated and it then returns to the above described step SP8.
- the CPU 36 enters the state where it waits for an input operation to the input operation unit 12 while repeating the updating of the judgment reference value by the loop of SP8-SP9-SP10-SP8.
- the CPU 36 makes a judgment at step SP14 as to whether the operation input result coincides with the master pattern.
- the CPU 36 Upon completion of such processing, the CPU 36 returns to the above described step SP8 to enter a new monitor cycle.
- the CPU 36 takes this into the mark operation information register RG2 and it compares this with the judgment reference value in the judgment reference value data register RG3 to thereby take the judgment result to the judgment result register RG4.
- Fig. 7 shows a case of applying the present invention to an onboard door lock system for electronically locking/unlocking the door of a car.
- the operation input unit 1 by introducing power for the operation input unit 1 by detecting the fact that a person has been approaching the car in addition to the construction of Fig. 1, the operation input unit 1 starts processing for reading to the image information memory 27 the video signal VD of the input operation unit 12 taken by the television camera 11.
- the CPU 36 judges this as that the switch has been operated for inputting and causes a panel switch output unit forming the response operation unit 41 via the control signal generation unit 40.
- the operation information obtained from the key positioned at the rightmost side among the keys hidden by the indicating stick 64, i.e., from the mark indication with the largest x-coordinate value is selected as a significant information at the operation position judgment unit 10.
- the image of the key input switch indication sheet 68 taken by the television camera 11 is not displayed on the monitor 16.
- the image of the key input switch indication sheet 68 may be displayed on the monitor 16 so that the operator is able to effect an input operation while checking such display.
